Switched to different set of tires with 12mm spacers and used the same bolts. Ultimately used bolts are an unknown quantity anyway if someone has used them a lot or over torqued them, you would not know. A new set will run you $20-$30 and are easy to get and rogue currently charges $150 shipped for 15mm spacer with bolts, so you still would end up with them with new bolts for half price.
